Описание
ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the JNG encoder when a blob cannot be opened. Attackers can trigger the memory leak by providing malformed JNG files that fail blob operations, causing resource exhaustion.
A flaw was found in ImageMagick. A memory leak vulnerability exists in the JNG (JPEG Network Graphics) encoder when the application fails to open a blob. A remote attacker could exploit this by providing specially crafted malformed JNG files, leading to resource exhaustion and a denial of service (DoS) for the affected system.
Отчет
Red Hat Enterprise Linux ships ImageMagick in RHEL 6 ELS and RHEL 7 ELS. This flaw has been rated as having a Low security impact and is not currently planned to be addressed in future updates of those products. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.
Меры по смягчению последствий
Do not process untrusted image files with ImageMagick. The JNG coder can be disabled in ImageMagick's policy.xml if not needed: <policy domain="coder" rights="none" pattern="JNG"/>. Upgrade to ImageMagick 7.1.2-26 or 6.9.13-51 mitigates the issue.
